OORBIN, OF SAME PLACE,

TRUNK-LOCK.

SPECIFICATION forming part of Letters Patent No. 239,937, dated April 12,. 1881.

Application filed November 15, 1880.

To all whom it may concern:

Be it known that I, GEORGE B. GowLEs, of New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Hasp-Locks for Trunks, of which the followingis a specification,

My invention relates to improvements in hasp-locks for trunks, in which a tumbler is hinged to the sides of the case by a narrow neck, which rests in a slot formed in said side. Said tumbler is also combined with a bolt and spring in. a peculiar manner hereinafter described.

The objects of my improvements are to so simplify the parts as to reduce the price in cost of construction, and also so as to render them more efficient. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure l is a front elevation with the front plate removed. Fig. 2 is a horizontal section of said lock, taken on line a a: of Fig. 1 and Fig. 3 is a section on line 3 y of Fig. 1.

The oscillating boltA is of a form, in its main features, of bolts which have heretofore been used in this class of locks. I hang this bolt within the case B by means of a small hook or lug, a, which rests in a slot made to receive it in one of the side walls of the case, and it hooks over said side at the bottom of the slot. It is provided on its front side with a stud or pin, 1). A small notch or opening is left upon one side of the case B, and a narrow neck, a, is formed at one end of the tumbler G, and said tumbler is pivoted to the case by merely placing it in position with the narrow neck resting in the slot in the side of the case B. The tumbler is also provided with a slot for the pin b of the bolt, which slot, like those in ordinary tumblers, has a straight portion and enlargements at each end, in which the pin plays when the bolt is oscillated, as in ordinarylocks. The opposite end of the tumbler has a small notch 'or recess, d, which receives one end of a flat spring, D, the other end of which spring rests in one corner of the case B, and the width of which spring is'such as will fill the space between the front and rear plates of the case. This spring has a constant tendency to force the tumbler downward and hold the tumbler into engagement with thepin on the bolt, so that the bolt and tumbler work together in the ordinary man- (MOIIBL) 0 ner. The bolt A has no spring acting directly upon it, and is held in its locked and unlocked position only by the tumbler.

Although I have described the bolt as an oscillating one, it is evident that the same manner of hanging the tumbler to the walls of the case and the arrangement of the spring to force the tumbler downward maybe employed in connection with a bolt of different construction.

By means of the improvement hereinbefore described I am enabled to construct the parts so that they can be 'put together by merely placing them in the proper position, and with but little or no fitting of the parts.

The spring is so combined with the tumbler as to depress it and not to be in the way of the hasp-staples or the operation of the bolt, and at the same time it is very easily and cheaply made and put in place.

I am aware that a spring has been made to work in connection with an oscillating bolt so arranged that one of its ends bore directly upon the bolt to throw it in either direction,

and the other end rested in the corner of the case, and I hereby disclaim the same.

I claim as my invention 1. The combination of a lock case and bolt with the tumbler 0. having the narrow neck 0, and hinged to the side of the case by resting the narrow neck in a slot in said side, in the manner substantially asdescribed, and for the purpose specified.

. 2. The combination of a lock-bolt and its case with the tumbler U, hinged thereto, and the spring D, with one end resting in the notch (1, near the end of the tumbler, and the other end at one corner of the case, substantially as described, and for the purpose specified.

3. The combination of the lock-case B and the oscillating bolt A, provided with hook a, resting in a notch in one side of the case, with the tumbler (J, hung to the lock-case, substantially as described, whereby it is prevented from longitudinalmovement, and the spring D, bearing upon the tumbler, but having no other connection with the oscillating bolt, all
